成员类型定义说明

Ptr

typedef std::shared_ptr<PeekableStream> sese::io::PeekableStream::Ptr

构造及析构函数说明

~PeekableStream()

virtual sese::io::PeekableStream::~PeekableStream ( )

virtualdefault

成员函数说明

peek()

virtual int64_t sese::io::PeekableStream::peek ( void * buffer, size_t length )

pure virtual

仅读取内容，不步进

参数

buffer	缓存
length	缓存大小

返回

实际读取大小

在 sese::_windows::iocp::v1::NativeContext, sese::io::AbstractByteBuffer, sese::io::AbstractFixedBuffer, sese::io::ByteBuffer, sese::io::FileStream, sese::io::FixedBuffer, sese::io::InputBufferWrapper, sese::io::StdInputStreamWrapper, sese::iocp::IOBuf, sese::iocp::v1::Context, sese::net::Socket , 以及 sese::res::ResourceStream 内被实现.

被这些函数引用 sese::io::InputStreamReader::readLine() , 以及 sese::internal::net::http::HttpClientImpl::writeBodyByData().

trunc()

virtual int64_t sese::io::PeekableStream::trunc ( size_t length )

pure virtual

仅步进，不读取内容

参数
